KBJL408G-BP

Overview

The KBJL408G-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components. It features an average forward current of 4 A and a peak repetitive reverse voltage of 800 V. The device utilizes glass passivated chip junctions for enhanced reliability. Key electrical specifications include a maximum non-repetitive surge current of 350 A, a forward voltage drop of 1.1 V at rated current, and a reverse leakage current of 5 µA. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction technology ensures high reliability and resistance to thermal stress.
• High surge current capability supports robust performance during transient load conditions.
• Low forward voltage drop contributes to improved efficiency in power conversion applications.

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific package variant, as MCC offers both standard KBJ and low-profile KBJL configurations. Confirm that the selected part matches the required PCB footprint and pin spacing. Check manufacturer documentation for the most recent lifecycle status, as availability may vary. Ensure compliance with RoHS directives if required by your assembly process.

Selection Notes

Select this component when a 4 A rating and 800 V blocking voltage are required in a compact form factor. Compare the KBJL series against the standard KBJ series to determine if the reduced height profile meets mechanical constraints. Verify thermal management requirements based on the specified operating temperature range and ambient conditions.

Part Context

This part belongs to the KBJL series of single-phase bridge rectifiers from Micro Commercial Components. The series is designed for through-hole mounting and combines high current density with reliable operation. It serves as a specialized variant within the broader KBJ family, offering distinct physical dimensions while maintaining similar electrical performance characteristics for general power applications.

Replacement Considerations

Direct substitutes include other 4 A, 800 V bridge rectifiers in compatible packages. Verify pinout compatibility and thermal resistance values before substitution. Consider the KBJ408G-BP if the standard height profile is acceptable. Always validate mechanical fit and electrical ratings against the original design specifications.
